I'm guessing the sudden change in clocks would be the perpetrator here. When it goes up, the voltage changes as well and perhaps not quick enough, so it would cause instability when overclocked. It works at stock speeds because it was designed to.

I'm thinking this...

It goes up and doesn't have enough voltage in that moment so it just crashes.
